4.12—Alkanes are used as fuels and obtained from the fractional distillation, cracking and reforming of crude oil

Know that alkanes are used as fuels and obtained from the fractional distillation, cracking and reforming of crude oil, and be able to write equations for these reactions.

Use —alkanes are used as fuels and obtained from the fractional distillation, cracking and reforming of crude oil to connect the rule to the data and decision in the question.

This matters because —alkanes are used as fuels and obtained from the fractional distillation, cracking and reforming of crude oil determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —alkanes are used as fuels and obtained from the fractional distillation, cracking and reforming of crude oil to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Alkanes are used as fuels and obtained from the fractional distillation, cracking and reforming of crude oil is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
